Ủng hộ nha
X x125 = ?

Không hiểu j hết trơn
Hình như là đề bài sai òi
X x125 = ?
trả lời
= 125 x
cho mình hỏi:
25 x 20 x 125 x 8 - 8 x 30 x 5 x125=?
GIẢI HỘ MÌNH NHÉ
\(25\times20\times125\times8-8\times30\times5\times125\\ =125\times500\times8-8\times150\times125\\ =125\times4000-1200\times125\\ =125\times\left(4000-1200\right)\\ =125\times2800\\ =350000\)
Tính
120 x 999 + 120
2 x 4 x 0,8 x 5 x 2,5 x125
\(\frac{120\times999+120}{2\times4\times0,8\times5\times2,5\times125}\)
\(=\frac{120\times1000}{\left(125\times0,8\right)\left(4\times2,5\right)\left(2\times5\right)}\)
\(=\frac{120000}{100\times10\times10}\)
\(=\frac{120000}{10000}\)
\(=\frac{12}{1}=12\)
Biết xo thỏa mãn (-64)x125=x3khi đó -5xo=.....?
(-64)x125=x3
-8000=x3
vì -8000=-203=>x=-20
vậy -5x0=-5.(-20)1=100
Bang 100
NHỚ CHO MK NHA !!!!!!!!!!!!!!!!
Biết xo thoa man:(-64)x125=x3 khi đó -5xo là gj?
(-64) . 125 = x3
=> \(\left(-4\right)^3.5^3=x^3\)
=> \(\left(-4.5\right)^3=x^3\)
=> \(\left(-20\right)^3=x^3\)
=> x = -20
=> -5x0 = \(-5.\left(-20\right)=100\)
(-64) . 125 = x3
=> $\left(-4\right)^3.5^3=x^3$(−4)3.53=x3
=> $\left(-4.5\right)^3=x^3$(−4.5)3=x3
=> $\left(-20\right)^3=x^3$(−20)3=x3
=> x = -20
=> -5x0 = $-5.\left(-20\right)=100$
Biết x0 thỏa mãn: (-64)x125=x3 khi đó - 5x0 = ...
x3=(-64).125
x3=-8000
=>x=-20
=>(-5).x=(-5).(-20)=100
tk nha bạn
